When you host your domain name on our servers, you have the ability to set up unlimited email aliases on that domain (e.g., me@mydomain.com). Email addressed to those email aliases will be automatically redirected to any email address you choose.
You can setup these email aliases by clicking on the "Email" link on your Store Manager page once your domain name is active for your Yahoo! Store site.
For each domain served by Yahoo! Store, you can forward email to one or more real email accounts.
An email account is not included with and is not available for your domain name when it is hosted on our servers. So you will need to have an active email account that can be set up to receive the emails sent to your email aliases.
